Athens is too much of a big stadium, they would never sell out the place, but they're already in a better position than the final turnout for 2022. It would make very little sense to invest on such a big support knowing you can't fill the place up anyway.Helloween have a headline show in Greece in July. So they can't be in Greece.
Some time ago there was a rumour about anthrax supporting in Greece. No idea though if there's any shread of truth in that.
Not saying it will happen, but given that some shows (Milan, Sofia, Lisbon, Bucharest) need a big boost and the availability of the band, it's a possibility, although small.
